The second rectangular hole 105a of the connecting angle steel 105 can be aligned with any one of the second positioning holes 201b-1 of the second longitudinal beam 201b, and a second bolt 204 passes through the second rectangular hole 105a and the second positioning hole 201b-1 aligned with each other to be fixedly connected, so that the second longitudinal beam 201b and the outer end of the cross bar 102 are fixed.

Since the longitudinal beams of the steel tread platform plate 200 of the present invention are arranged with a plurality of positioning holes, the triangular support assembly 100 can be flexibly selected or adjusted in installation position.

In addition, the device can be repeatedly recycled only by installing two layers, so that materials and labor are saved, and the construction cost can be reduced.

In another embodiment, as shown in fig. 9 to 11, the supporting platform of the present invention further includes a sliding extrusion assembly 400, which can be used to quickly fix two ends of the diagonal rod 103 to the vertical rod 101 and the horizontal rod 102, respectively, so as to quickly mount and fix the diagonal rod 103, thereby saving the mounting time.

The upright rods 101 and the cross rods 102 are both made of channel steel C, a channel type sliding channel C-1 is arranged in the channel steel C, strip-shaped bulges C-2 protruding inwards are symmetrically arranged at the outer edges of legs at two sides of the channel steel C (namely two side plates of the channel steel C), and the extending direction of the strip-shaped bulges C-2 is consistent with the length direction of the channel steel C. The bottom of the inner side of each channel steel C is provided with positioning teeth C-3 which are arranged along the length direction of the channel steel C, the positioning teeth C-3 are tooth-shaped bulge structures which are arranged at equal intervals, and two side surfaces of each positioning tooth C-3 are respectively a positioning surface C-31 and a guide slope surface C-32; the positioning surface C-31 is closer to the vertical intersection point of the vertical rod 101 and the cross rod 102 relative to the guide slope surface C-32, and the positioning surface C-31 is a plane perpendicular to the length direction of the channel steel C; the guide slope surface C-32 has a tendency to approach the positioning surface C-31 from the inside to the outside so that the width of the outer end of the positioning tooth C-3 is smaller than the width of the inner end.

The diagonal rod 103 of the present invention may be a hollow square tube with both ends sealed. Preferably, the thickness of the diagonal rod 103 is matched with the interval between the two strip-shaped bulges C-2, and the peripheral outline of the two ends of the diagonal rod 103 is an arc convex curved surface of a semi-cylindrical surface.

The sliding squeeze assembly 400 includes a housing 401 slidably disposed in the sliding channel C-1, a positioning member 402 having one end movably disposed in the housing 401 and the other end capable of protruding out of the housing 401, and an elastic member 403 capable of pressing one end of the positioning member 402 out of the housing 401.

Wherein, the shell 401 is a hollow box shape which is matched with the width of the sliding channel C-1, the two sides of the shell are provided with sliding grooves 401a which are matched with the strip-shaped bulges C-2, and the shell can slide in the sliding channel C-1 linearly through the matching of the strip-shaped bulges C-2 and the sliding grooves 401 a. The housing 401 is further provided with a window 401b corresponding to the positioning member 402, one end of the positioning member 402 is movably disposed in the housing 401, and the other end of the positioning member 402 can extend out of the window 401b under the extrusion of the elastic member 403, and the elastic member 403 is a metal elastic sheet fixed on the inner side wall of the housing 401. As shown in FIGS. 11(b) -11 (C), the outward extending end of the positioning member 402 can slide over the guiding slope C-32 of the positioning tooth C-3 to rest on the positioning surface C-31 of the positioning tooth C-3. Based on this, under normal conditions, the sliding extrusion assembly 400 can only slide in one direction in the sliding channel C-1 through the cooperation of the protruding end of the positioning member 402 and the positioning tooth C-3, specifically: the sliding squeeze assembly 400 inside the upright 101 is only capable of one-way sliding upwards; the sliding squeeze assembly 400 within the crossbar 102 is only capable of unidirectional sliding inward (in a direction closer to the uprights 101).

When the inclined rod 103 is installed, two ends of the inclined rod 103 can be respectively embedded into the vertical rod 101 and the sliding channel C-1 of the cross rod 102; then, taking a sliding extrusion assembly 400 and sliding the sliding extrusion assembly upwards into the sliding channel C-1 of the vertical rod 101 so as to enable the sliding extrusion assembly to be propped against the lower end of the inclined rod 103; next, a sliding squeeze assembly 400 is again taken and slid inwardly into the slide channel C-1 of the crossbar 102 so that it abuts the upper end of the diagonal bar 103. Therefore, the inclined rods 103 are extruded and limited through the two sliding extrusion assemblies 400, and the inclined rods 103 can be rapidly installed between the vertical rods 101 and the cross rods 102. As shown in fig. 9, since the inclined rod 103 is obliquely arranged, a triangular stabilizing system can be formed after two ends of the inclined rod are tightened, so that the installation is fast and the structural stability can be ensured. Preferably, the housing 401 is a detachable structure including a hollow case opened at one side and a cover plate capable of being fixed to the opened side of the hollow case by screws.

Further, the sliding squeeze assembly 400 further includes an adjusting member 404 and a driving member 405.

The positioning member 402 includes a first section 402a, a second section 402b engaged with one end of the first section 402a, and a pressing head 402c engaged with the other end of the first section 402 a. The first section 402a and the second section 402b are both plate structures, and the second section 402b is bent inward relative to the first section 402 a. The extrusion head 402C has a tendency to bend outwardly relative to the first section 402a and the extrusion head 402C is able to protrude out of the window 401b to engage the positioning teeth C-3, acting as a detent.

The joint of the first section 402a and the second section 402b is provided with a convex rotating shaft 402d, the rotating shaft 402d is embedded in a movable groove 401c arranged on the inner side wall of the shell 401, and at least self rotation can occur in the movable groove 401 c. Preferably, a pair of protruding shafts 402d are symmetrically disposed on two sides of the joint of the first section 402a and the second section 402b, and correspondingly, a pair of movable grooves 401c are symmetrically disposed on the inner sidewall of the housing 401.

The housing 401 is provided with a screw port 401d that is through inside and outside, and the outer side wall of the adjuster 404 is provided with a male screw that fits into the screw port 401d and is rotatably provided in the screw port 401 d. In addition, an annular groove 404a is provided at an end of the adjusting member 404 extending into the housing 401.

One end of the driving element 405 is a connection ring 405b which is matched with the annular groove 404a, and is sleeved in the annular groove 404a (can rotate relatively) through the connection ring 405b, the other end of the driving element 405 is a pull frame 405a which can surround the periphery of the second section 402b, and the inner width of the pull frame 405a is matched with the width of the second section 402 b. Therefore, when the adjusting member 404 is rotated, the adjusting member 404 can drive the driving member 405 to move up and down together, but the driving member 405 cannot rotate together with the adjusting member 404 due to the limitation of the second section 402b on the pull frame 405 a.

The elastic member 403 is a metal elastic sheet fixed on the inner side wall of the housing 401, and presses the inner side surface of the extrusion head 402c, so as to push the extrusion head 402c out of the window 401b, and meanwhile, the elastic member tends to push the extrusion head 402c away from the adjusting member 404. Therefore, as shown in fig. 11(C), when the adjusting member 404 is rotated and pulled downward by the pulling frame 405a to pull the second section 402b, the positioning member 402 can rotate around the rotating shaft 402d as a rotating center, so that the pressing head 402C can more tightly press on the spacing side J between the adjacent positioning teeth C-3 to prevent the positioning member 402 from being released.

Preferably, the width of the movable slot 401c is matched with the outer diameter of the rotating shaft 402d, and the length of the movable slot 401c is larger than the outer diameter of the rotating shaft 402 d; the length direction of the movable slot 401C is the same as the length direction of the channel steel C where the sliding extrusion assembly 400 belongs. Therefore, the rotating shaft 402d can slide to some extent in the movable groove 401c as well as rotate by itself in the movable groove 401 c. Based on this, according to the above process: when the extrusion head 402C presses on the spacing side J between the adjacent positioning teeth C-3, if the adjusting member 404 is continuously rotated, as shown in fig. 11(d), due to the arrangement of the movable slot 401C, the pulling frame 405a can also continuously pull the second section 402b downward, the vertical pressing force of the extrusion head 402C on the elastic member 403 is increased, and the extrusion head 402C can be pressed on the spacing side J between the adjacent positioning teeth C-3 with greater force under the guidance of the elastic member 403; the adjusting member 404 is still rotated continuously, when the extrusion head 402C contacts the positioning surface C-31 of the positioning tooth C-3 below the extrusion head, the pulling frame 405a cannot pull the second section 402b continuously downwards, and the extrusion head 402C can be tightly pressed on the positioning surface C-31; if the adjusting member 404 is rotated continuously, since the positioning member 402 can not move continuously, the adjusting member 404 can reversely drive the housing 401 to slide upwards slightly through the threaded fit between the adjusting member and the threaded opening 401d, so that the housing 401 tightly extrudes the end of the diagonal rod 103, the two ends of the diagonal rod 103 are clamped and limited, and the final stability of the structure is ensured. The maximum effect of the stroke action is as follows: since the diagonal rod 103 is pushed and clamped by the sliding compression assemblies 400 at both ends thereof, and the sliding compression assemblies 400 are positioned by the limitation of the compression heads 402C between the adjacent positioning teeth C-3, the fixed positions of the sliding compression assemblies 400 in the sliding channel C-1 are interval and discontinuous, so that when the sliding compression assemblies 400 compress either end of the diagonal rod 103, there is a space for movement, the housing 401 can be driven reversely by rotating the adjusting member 404 to compress the end of the diagonal rod 103, so as to achieve the final structural stability.

Further, the sliding extrusion assembly 400 further comprises a retreat rod 406 with a rod-shaped structure, which is used for unlocking and retreating the sliding extrusion assembly 400 which originally can only move in one direction in the sliding channel C-1, so as to facilitate the disassembly and recovery of the sliding extrusion assembly 400 and the inclined rod 103.

The interior of the adjustment member 404 has a passage 404b therethrough along its length, the passage 404b fitting to the outer diameter of the parking rod 406. The retreat lever 406 passes through the channel 404b, and is provided with a limiting head 406a at the inner end thereof and a pressing head 406b at the outer end thereof, wherein the limiting head 406a and the pressing head 406b are disc-shaped structures with outer diameters larger than the outer diameter of the main body of the retreat lever 406.

A return spring 407 is further provided on the outer periphery of the retraction lever 406, and one end of the return spring 407 presses the pressing head 406b and the other end presses the outer sidewall of the housing 401. In a natural state, the return spring 407 enables the stopper 406a to be pressed and caught on the inner end of the adjuster 404.

When the sliding compression assembly 400 and the diagonal rod 103 need to be disassembled, the adjusting member 404 can be rotated reversely to gradually enter the interior of the housing 401, so that the pulling action on the second section 402b can be released by the pulling frame 405 a; at this time, if the pressing head 406b of the retraction lever 406 is manually pressed, the limiting head 406a can push the second section 402b to rotate reversely, so that the pressing head 402C retracts into the window 401b, and the limitation of the positioning teeth C-3 is released, therefore, the sliding pressing assembly 400 can slide out along the sliding channel C-1, and the detachment is realized.
